Hwashin technology, korea was established in 1980 in the field of ultrasonic cleaning systems. This system is faster, more thorough and safer than any other method-scrubbing, soaking, stream and so on. Ultrasonic sound waves moving through a cleaning solution create an effect called cavitations, the rapid formation and implosion of microscopic bubbles. Heat enhances the process. The deep cleaning action of ultrasonic removes even the most stubborn dirt and contaminants. Digital sonicators are available in two types digital ultrasonic bath [sonicator] and digital pipette washer.
